Maki's place is super convenient: 3 minutes walk to Chong nonsi BTS, it's just a few stops to Siam station, 24 hours convenience stores just downstair, super fast elevator, lots of street food around.
The place is very clean and tidy. Kettle, microwave oven, and washing machine are available. Cups and bowl are provided, no chopstick and spoon so you have to buy. There are umbrellas, too. Definitely recommended and will stay here if I had the chance to come to Bangkok again.
